In the process of cleaning the floor by the cleaning piece, the dirt scraping piece is required to be utilized to scrape the sewage and the adhered dirt on the cleaning piece synchronously, the surface of the cleaning piece is easy to wind with the hair, the thread end and other foreign matters, and in order to clean the foreign matters wound on the cleaning roller, the comb teeth are further arranged on the ground brush, and the foreign matters on the cleaning roller are scraped through the comb teeth.

A comb structure is disclosed in the prior art, as in application number CN201711481216.4, which extends into the cleaning roller and provides an angled leading edge by which the windings on the rotating cleaning roller are removed. On the one hand, because the rotation speed of the roller brush is relatively fast, partial windings possibly exist, because the windings are too tightly attached to the outer surface of the roller brush and cannot be removed by the comb teeth for the first time, the windings continue to rotate under the driving of the roller brush, and when the windings are once passed over the comb teeth and wound on the roller brush for a circle, the windings are difficult to remove from the surface of the roller brush, and the windings are more tightly wound, so that the subsequent cleaning effect of the roller brush is affected, and a user is required to manually remove the windings, so that the roller brush is inconvenient to use. On the other hand, the front edge extension line of the comb teeth is close to the rotation center of the cleaning roller, so that the rotation resistance of the comb teeth to the cleaning roller is relatively high, and the service life of a driving motor of the cleaning roller is influenced.

The technical effects of this embodiment are explained below with reference to fig. 5:

When the roller brush drives the windings to rotate, the cleaning piece is contacted with the tooth tips of the comb teeth, and most of hair windings C1 on the cleaning piece can be peeled off in advance through the tooth tips of the comb teeth, so that the first-stage peeling is realized. In this process, there may be a small portion of the wound C2 that fails to be peeled off by the first stage and passes over the second stage, and since the pressing force between the second stage and the bristles of the roller brush becomes small, the bristle deformation becomes small, and the pressure of the wound C2 is released, so that the wound C2 is loosened or loosened from the roller brush, and especially the front end of the wound C2 is separated from the bristles, and continues to move upward along with the roller brush to the dirt scraping member, and since the deformation of the dirt scraping member abutting against the roller brush is greater than that of the first stage and the second stage, the dirt scraping member deeply presses the dirt scraping roller brush, and the dirt scraping member starts to separate and peel from the front end of the wound C2, preventing the wound C2 from passing over the dirt scraping member, thereby realizing the second stage peeling. That is, in this embodiment, the winding is peeled off in two stages, i.e., one stage and two stages, so that the winding can be better prevented from passing over the dirt scraping member.

In order to improve the cleaning effect of the surface to be cleaned, the cleaning piece of the roller brush is made of water-absorbing fiber materials, a water distribution piece 8 is further arranged above the dirt scraping piece 5, a water supply port 81 for supplying cleaning liquid to the roller brush is arranged on the water distribution piece 8, and the brushing hair of the roller brush after water absorption has better effect of wiping stains on the surface to be cleaned. The lower surface of the dirt scraping piece 5 is at least partially jointed with the upper surface of the comb tooth piece 6, and the upper surface of the dirt scraping piece is at least partially jointed with the lower surface of the water diversion piece 8. As an improvement, the dirt scraping piece and the comb tooth piece can be of an integrated structure. It will be appreciated that when the roller brush is in a dry state in which it is not absorbing water, the bristles of the cleaning element are in a fluffy state, at which point the roller brush has a maximum profile range, and the comb teeth and the dirt scraping element extend into the bristles of the roller brush. When the roller brush is in a water absorption state, bristles of the cleaning piece can fall down after being scraped with a surface to be cleaned or the comb teeth and the dirt scraping piece, so that the actual contour range of the roller brush is reduced to be smaller than the maximum contour range but larger than the contour range of the roller shaft.

In this embodiment, the plurality of teeth 61 on the comb member 6 are arranged at intervals along the axial direction of the roller brush, the teeth 61 of the comb member 6 at least partially extend into the bristles 41 of the roller brush 4, the teeth 61 include rear tooth surfaces 617 facing away from the roller brush 4 and front tooth surfaces facing the roller brush, the front tooth surfaces form the carding surfaces 616, the front tooth surfaces 616 extend from tooth tips 618 of the teeth to the lower surface of the dirt scraping member 5, tooth grooves between the teeth also extend to the lower surface of the dirt scraping member, the first end and the second end are formed on the front tooth surfaces, and deformation amounts of the front tooth surfaces 616 abutting against the roller brush decrease along the direction from the tooth tips 618 to the dirt scraping member 5. In particular, the carding surface may be curved, planar or a combination.

To further enhance the removal of the entanglement, the comb teeth 61 extend downwardly and at least partially block the dirt pick-up opening 24, as shown in figures 3 and 7. When the surface cleaning device cleans the surface to be cleaned, the dirt suction fan works, so that the effective area of the dirt suction opening is reduced, the wind pressure at the dirt suction opening which is partially shielded by the comb teeth is increased compared with the dirt suction opening which is not shielded by the comb teeth, most of dirt liquid, dirt, hair and other winding matters sucked from the surface to be cleaned to the dirt suction opening can easily enter the dirt suction opening, and the first-stage supercharging is realized. Preferably, a portion of the connecting portion 62 also extends downward to at least partially block the dirt pickup opening 24, and a lower end of the connecting portion 62 is lower than an upper end of the dirt pickup opening 24, thereby further increasing the first stage supercharging effect.

Referring to fig. 7 and 8, the comb teeth 61 include a penetrating section 611 and a guiding section 612, a gap 613 penetrating through the carding surface 616 and the rear tooth surface 617 is formed between two adjacent penetrating sections, the gap 613 of two adjacent penetrating sections 611 forms a slit effect area (such as a rectangular dotted line frame in fig. 2 and an oval dotted line frame in fig. 7) at the dirt suction opening 24, when the dirt suction fan works, the wind pressure at the gap 613 increases and the wind speed is also increased, and the wind pressure near the dirt suction opening which is not covered by the comb teeth is smaller than the wind pressure at the position, so that unbalanced airflow is generated at the dirt suction opening, and the wind such as the hair in the comb teeth gap, dirt and dirt liquid are smoothly sucked into the dirt suction opening by the faster wind speed under the action of the larger wind pressure of the unbalanced airflow, thereby further improving the dirt suction efficiency, so as to realize the second stage supercharging, and to better prevent the wind from crossing the dirt scraping piece, and prevent the hair and solid dirt from accumulating in the gap of the comb teeth, especially, and especially have better dirt stripping and dirt suction effect for the dirt or the dirt retaining effect on the comb teeth, thereby bringing good customer experience.

The liquid flowed through the tube and passed through the stenosis at an increased flow rate. The flow rate of the gas stream is also increased by the flow of similar liquids in the tube as the ground passes over narrow terrain, and the density is also increased by the compressibility of the gas. The effect of such topographical canyons on airflow is known as the "slot effect," also known as the "canyon effect. The slit effect in the utility model is the same as the canyon effect in daily speaking, and refers to the phenomenon that wind sucked into a roller brush cavity from the position between a roller brush of a ground brush and a ground scraping strip moves to a dirt sucking port and encounters a gap between comb teeth covering the dirt sucking port, and the wind speed is increased and the wind pressure is increased when the wind passes through the narrower gap due to the narrower gap. The slit effect area of the utility model refers to an area formed by gaps between two adjacent comb teeth, wherein the comb teeth partially cover the dirt absorbing opening, and the adjacent comb teeth are arranged corresponding to the dirt absorbing opening. For example, there are 8 comb teeth covering the dirt sucking mouth, there are 7 comb teeth gaps in the 8 comb teeth, and the area formed by the 7 gaps is the slit effect area.

To increase the slit effect area, the dirt pick-up efficiency is improved, and at least part of the comb teeth 61 is higher than the dirt pick-up opening. Specifically, the comb teeth 61 are located in front of the dirt absorbing port 24, tooth grooves between the comb teeth extend to the lower surface of the scraper, the top end of the front tooth surface 616 is higher than the dirt absorbing port 24, and the comb surface 616 extends downwards from the outer side of the dirt absorbing port 24 to at least partially shield the dirt absorbing port 24.

In order to further improve the dirt sucking efficiency of the slit effect area, a dirt passing channel is further arranged between the roller brush and the tooth groove, so that the windings stripped by the dirt scraping piece and the scraped dirt liquid can flow downwards along the dotted line direction shown by the hollow arrow in fig. 3 through the dirt channel. As one mode of this embodiment, when the roller brush is in a dry and fluffy state without absorbing water, the bristles are in contact with the bottom surface of the tooth groove so as to block the dirt passage; when the roller brush is in a water absorption state, the brush hair of the cleaning piece can fall down after being scraped with the surface to be cleaned or the comb teeth and the dirt scraping piece, and at the moment, a dirt passing channel between the outer surface of the roller brush and the bottom surface of the tooth groove is opened. As another way of this embodiment, the bristles do not block the dirty channel in a dry fluffy state in which water is not absorbed by the roller brush.

As shown in fig. 3, 5, 8, the comb teeth 61 are inclined downward with respect to the horizontal plane and extend toward the roller brush 4 side. In this embodiment, the longitudinal section of the comb teeth is triangular, the comb teeth 61 have a comb surface 616 inclined downward and a rear tooth surface 617, and the extension surface JK of the front tooth surface 616 is separated from the outer surface of the roller shaft. As shown in fig. 3, the front surface of the comb element 6 or the extension JK of the front tooth flank is offset from the outer surface of the roller shaft, so that the extension passes only through the bristle field. Therefore, under the condition that the distance between the tooth tips of the comb teeth and the rotation central axis of the roller brush is fixed, the length of the comb teeth in the maximum outline range of the roller brush can be longer, the contact area of the comb teeth and the comb hair is larger, the change of the extrusion force of the front tooth surface and the roller brush is relatively continuous, the pressure release is stable, and the stripping treatment effect on the windings on the roller brush is better. And obvious tooth marks can not be generated on the base material, and the movement resistance of the comb teeth to the roller brush is small, so that the service lives of the brush hair and the driving motor of the roller brush are prolonged. In addition, the length of the comb teeth covering the dirt absorbing opening is enough, so that a slit effect is easy to generate, the surface cleaning device is not only beneficial to sucking larger garbage from the surface to be cleaned, but also can form a stronger slit effect at the position of the comb teeth covering the dirt absorbing opening, so that a stronger suction force is generated, and the cleaning suction effect on dirt or dirt liquid or wound scraped by the comb teeth and the dirt scraping piece is also better.

Specifically, the carding surface 616 is inclined downward along the top 241 of the dirt absorbing port 24 by an angle gamma of 70 degrees less than or equal to gamma less than 90 degrees, so that the tooth tips of the comb teeth are reasonable in position tangential to the base material of the roller brush, the length of the comb teeth in the brush hair of the base material is reasonable, the comb teeth can effectively peel off wound matters such as wound hair on the roller brush, too many and even tooth marks are not formed by the comb teeth in contact with the base material, and the service life of the roller brush is influenced. The rear tooth surface 617 is arranged in a downward inclined manner along the connecting part 62, the rear tooth surface is inclined away from the direction of the roller brush, and the extension surface of the rear tooth surface is intersected or tangent with the outer surface of the roller shaft, so that the sewage and the dirt can easily and smoothly move to the vicinity of the sewage suction port, and the guiding effect is good.

In this embodiment, the floor scraping strip 28 is located below the dirt absorbing opening 24 and forms a dirt absorbing nozzle 29 with the roller brush 4, and the comb member is provided with a guiding part facing the dirt absorbing nozzle. Through setting up the guide part, reduced the stay and the adhesion of dirty liquid and filth in dirt absorbing mouth department, most dirty liquid and filth can more effectively quick, smooth and easy entering pass dirt absorbing mouth by the dirt absorbing mouth department that is sheltered from by the broach and continue upwards to send to in the dirt holding bucket, improved dirt absorbing efficiency. Specifically, the comb teeth 61 include a rear tooth surface 617 facing away from the roller brush 4 and a combing surface 616 facing toward the roller brush, the combing surface and the rear tooth surface extending obliquely downward from the connecting portion and meeting to the tooth tip, and the rear tooth surface 617 being inclined toward the dirt suction port 24 and forming the guide portion. As an improvement on the rear tooth surface 617, the rear tooth surface 617 of the comb tooth 61 is formed by connecting a first inclined surface 6171 and a second inclined surface 6172, the first inclined surface 6171 is connected with the connecting part 62, the inclined angle of the first inclined surface 6171 is beta, wherein gamma is less than or equal to beta is less than or equal to 90 degrees, and the inclined angle beta of the first inclined surface 6171 is more than or equal to the inclined angle of the front tooth surface 616 and is at most 90 degrees. The included angle between the second inclined plane 6172 and the horizontal plane is θ, so that the inclined angle θ of the second inclined plane 6172 is θ, and the inclined angle θ of the second inclined plane 6171 is equal to or less than 30 ° and equal to or less than 35 °, in this embodiment, the inclined angle θ of the rear tooth surface 617 refers to the inclined angle θ of the second inclined plane 6172, therefore, under the guiding effect of the inclined angle θ of the second inclined plane 6172, the dirt liquid and the dirt are easier and more difficult to move to the vicinity of the dirt absorbing port, the angle just conforms to the angle formed by the dirt absorbing hose passing through the dirt absorbing port from the rear part of the accommodating cavity upwards and the dirt absorbing pipe on the dirt accommodating barrel, so that the guiding effect is good, and the first inclined plane 6171 plays a good blocking and steering effect when the liquid flowing backwards more than the liquid flowing across the comb teeth 61, especially has a good blocking and steering effect on the liquid flowing upwards after being extruded along the space between the comb teeth and the dirt absorbing port, the dirt absorbing port is more easily moved to the dirt absorbing port again after the liquid flowing back, the dirt absorbing hose passes through the dirt absorbing port, the dirt absorbing port is just in the dirt absorbing port, the dirt absorbing hose is more smoothly, and the dirt absorbing and dirt is more efficiently flowed into the dirt absorbing and dirt absorbing pipe is more smoothly. In the present embodiment, the inclination angle γ=84° of the front tooth surface, the inclination angle θ=33° of the second inclined surface, the inclination angle β=90° of the first inclined surface.
